Saw a product yesterday using nano tech to waterproof any electronic device The real deal was to see a I phone placed under several feet of water and left there for hours the phone was on the entire timethe phone never missed a beat the cost is about $60.00 which is a lot less than a new mobil phoneThis could be a new age in hobie safety with the ability to call help if needed My VHF radio is great however a waterproff I phone 4s would be better most of the timeFormer Hobie Admiral Gary

The aviation industry uses a product called carbon-X. They spray down all their electronic boards before they put the covers on. They also use it extensively for spaying servos, ECS's, and receivers in the word of R/C. You would have to find a way to get it into the phone.

I would be skeptical of "spray on magic". I don't know about other phones, but my iPhone has a headphone plug, volume button and silence switch, not to mention the USB data plug, none of which are waterproof; I can't imagine a spray product would let these remain operational...

I use a LifeProof case (http://www.lifeproof.com/) for my iPhone. It's completely water, dust, & shock proof, and they even make an armband and headphone adapters for it. I've had it underwater countless times with no problems.

Look into the Casio G'Zone from Verizon. It's an Android smart phone designed for US army specs. It's got guerilla glass for a screen, it's drop proof, and waterproof.

I have the Casio Commando (smart phone), and have owned the older versions as well. These phones are great. Water, dust and drop proof. I routinely go wading while fishing with my phone in my pocket. Once won $20 in a bet that I wouldn't drop my phone from shoulder height onto a concrete floor. The case is a little scuffed up, but that's it. My only complaints are that the gorilla glass makes the touch screen less sensitive, and it's slower than comperable smart phones. It's a great phone for anyone who needs a tough, durable phone.
